Flower Size 1" [2.5 cm]

Found in Costa Rica in humid premontane forests at elevations around 1160 meters as a mini-miniature sized, cool growing epiphyte with a simple, cane-like, terete, erect stem carrying 3 to 5, all along the upper 1/2 of the stem, fleshy, pale green to glaucous, infundibuliform, ovate to narrowly-ovate, obtuse bilobed, articulate, variable in size, the lower one smaller, minutely rugose, basally clasping leaves that blooms in the fall on a terminal, from a mature stem, occuring only once, short, subumbellate, lax, simultaneously 2 flowered inflorescence arising on a mature stem without a spathe, and only with an acute, amplexicaul, much shorter than the ovary floral bract.

"Epidendrum bogarinii belongs to the GROUP Difforme which is characterized by the caespitose, sympodial plants, fleshy, pale green to glaucous leaves, apical inflorescence, sessile, rarely with a short peduncle, one-flowered to corymbose, without spathaceous bracts, fleshy, green to yellowish-green rarely white flowers. The species can be recognized by the small plants, with 3 to 5 leaves with infundibuliform sheaths, two, simultaneous flowers, sepals .4 to .52" [10 to 13 mm] long, a minutely rugose ovary and column (ventrally), and a 3-lobed lip, erose margins, mid-lobe deeply emarginate, forming two semi-orbicular lobes. It is most similar to Epidendrum anastasioi Hágsater which has larger plants with more and larger elliptic leaves 1.8u to 2.8" [4.5 to 7 cm] long, 15 to 22 flowered inflorescences a glabrous ovary and column, narrower sepals and petals and a wide sinus between the apical lobes of the lip. Epidendrum chlorocorymbos Schltr. has much larger plants, does not have infundibuliform leave-sheaths, 5 to 20 flowered inflorescences, larger flowers with sepals and petals .52 to .77" [13 to 19.3 mm] long and the lip margin is entire. Epidendrum carnevalii Hágsater & L.Sánchez from the Caribbean slope of Colombia and Venezuela has taller, laterally compressed stems 5.6 to 10" [14 to 25 cm] long, with 4 to 12 leaves, inflorescences have 5 to 10 flowers and sepals are .52 to .72" [13 to 18 mm] long, the column and ovary are papillose, the lip has 1 to 3 thickened veins on the disc, margin is undulate, and the mid-lobe is short, emarginate, forming a pair of wide, divergent lobes. Epidendrum difforme Jacq. is endemic to the Windward Antilles of Montserrat, Guadelopue, Dominica, Martinique, St. Lucia, St. Vincent and Trinidad & Tobago; ancipitose stems are 4 to 10 leaved, inflorescence 2 to 5 flowered, lip is bicallose, the calli small, parallel, disc is thickened to form a low rib, margin of the lateral lobes is entire to crenate, that of the mid-lobe is entire, ovary and column are glabrous, and the clinandrium hood is funnel-shaped, the margin erose-dentate."
